And for folks who don't have time to read ~500 words, here are the two key points:

It turns out that Mark Zuckerberg is a great CEO--one of the two best in the tech industry (Jeff Bezos is the other). Why? A combination of several things: 1) Innate product genius, 2) hugely ambitious long-term vision, 3) ability to attract a great team to execute the vision, 4) lack of concern about short-term shareholder demands that would detract from that vision, 5) Patience.

For Mark Zuckerberg, Wall Street and normal concepts of "shareholder value" are, at best, a secondary concern. This attitude will, at some point, drive Wall Street crazy. But Zuckerberg owns 57% of Facebook's voting stock, so investors who don't like how he looks at the world can shove off.

Okay, one more: Mark Zuckerberg's priorities for Facebook--products and users first, business and shareholders second--are actually healthy and admirable. The country and the economy would be significantly better off if more CEOs thought this way.
